	For libdwarf producers and consumers

	The interface is defined as having 8-byte signed and unsigned
	values so it can handle 64-or-32bit target on 64-or-32bit host.
	Addr is the native size: it represents pointers on
	the host machine (not the target!).

	This contains declarations for types and all producer
	and consumer functions.

	Function declarations are written on a single line each here
	so one can use grep  to each declaration in its entirety.
	The declarations are a little harder to read this way, but...
